There has been a lot of worry and controversy surrounding vermiculite attic insulation over the past couple of decades. Why?
Before 1990, most of the world’s vermiculite was extracted from a mine in Libby Montana, sold under the brand name Zonolite® and later found to contain 1–3% asbestos. This type of insulation was mostly used in attics. Vermiculite can also be found behind walls, around electrical components, and even within concrete block-wall construction.
As such, older homes and buildings (those built between the 1940s and 1990s) are at a higher risk of containing asbestos-contaminated vermiculite insulation.
If you are in doubt, your safest bet is to schedule professional vermiculite testing in Ottawa with the experts at Mold Busters. Vermiculite testing in Montreal is also available.
Asbestos contamination can risk serious health concerns for families and many prefer to clean up vermiculite to remove any risk. Asbestos has been linked to serious health concerns, such as asbestosis, mesothelioma, and lung cancers.
To ensure the most accurate results, we take a minimum of four different samples of the insulation throughout the area of concern. In some cases, we may also set up a containment unit and run a HEPA air scrubber. We always wear the recommended personal protective equipment (PPE) when collecting samples of vermiculite insulation.
With quick turn around times from certified labs, Mold Busters has worked with partners and landlords to ensure that the risk posed by vermiculite is minimized and controlled in a cost-effective way.
If asbestos is confirmed to be present within the collected vermiculite samples, Mold Busters experts are trained to educated you about the real dangers, and what the next steps ought to be.
Mold Busters will always recommend the most effective methods for ensuring safety within the property is secured for all involved.

What is vermiculite?
Vermiculite is a mineral used in a variety of commercial and consumer products for its unique fire-resistant properties, which make it a great insulator.
Because of this, vermiculite was once a very popular option for loose-fill insulation in attics. It can also now be found in a number of items like acoustic panels, gas fireplaces, insulating concrete, brake linings in cars, fireproofing wallboard, soil fertilizers, packing materials and firestop pillows.
It’s important to remember that vermiculite in its pure form is not dangerous. What’s more, not all products that have vermiculite as an ingredient contain asbestos. The products of biggest concern are loose-fill or blow-in attic insulation.
Once again, if you have any doubts, don’t hesitate to contact an expert for professional vermiculite testing and analysis.
Much like surface sampling for mold, a vermiculite test involves taking a sample of the suspected material and sending it to an accredited lab for analysis. The results of this testing will reveal whether or not the insulation contains any asbestos fibres.
Safety tips for handling vermiculite
Aside from getting a professional vermiculite test, you can also take these simple steps to reduce the health risks associated with exposure to asbestos-containing vermiculite.

- Wear a respirator mask, gloves, long sleeves, and protective goggles if going near the vermiculite.
